You can change which directories are monitored with the
You can specify multiple directories by separating them with a space.
spacecheck_dirs = /var/lib/pgsql /var/spacewalk /var/cache /srv

You can change this behavior with the

Any other value disables it.
spacecheck_shutdown = true
The space checking tool is enabled by default. You can disable it entirely with these commands:
systemctl stop spacewalk-diskcheck.timer systemctl disable spacewalk-diskcheck.timer
